I am impressed by the massive amount of reviews. Some of the reviews are very well writen and good references.
However, I am REALLY skeptical about the value for horizontal comparisons among the IEMs based on the scoring. Take IE8 as an exmple which scored 9.0 for sound quality. And a bunch of those that are etiher in the same price range or below are scored equal or higher than IE8 including those that are clearly not in the same league in terms of sound quality, eg. XBA4, RE262/272, GR07, EX600, etc. Some of the phones are also clearly not even comparable to some scored lower, such as Turbine pros, Miles Davis and MG7.
Thus looking at the appendixed scoring charts can be quite confusing.
I don't understand what you're saying. Every phone you just listed sounds better than the IE8, which is in turn better than the MG7.
